Don:
I had what I believed was a leak coming from the tiller base plate and the pipe for the shaft for the rudder. The two forward scuppers were not draining properly and the cockpit was filling with water. Once it got up to the level of the base plate, etc. (about 1" - 1 1/2") it dripped down into the bilge.
Once I solved the scupper issue by replacing and reconfiguring the seacock hoses, I caulked all around the tiller base plate and the rudder shaft pipe with BoatCaulk. Since them, my bilge has been "essentially" bone dry even after sustained heavy rains - my Ty is moored in South Florida. With the constant humidity nothing is ever really dry.
I should note that once I fixed the scupper draining issue I probably did not have to worry about water ingress through the tiller base plate, rudder shaft pipe, etc., because thereafter no water accumulated in the cockpit. However, it was recommended to me by several on this board that these areas be well sealed as well. I did as suggested and am a happy camper.
Before taking on the task of removing the base plate, pipe, etc., I would first try to determine the real source(s) and cause(s) of the leak(s). Is your Ty on a mooring, at a dock or on a trailer

Does the cockpit fill with water after a rain

If so, the correct diagnosis may be something other a leak at the base plate, pipe, etc. These may be the areas where the leak(s) shows up, but the originating cause may be else where.
Having stated all of the above, please note that I am truly a "tadpole sailor" and have very, very little knowledge of sailboat repair and maintenance. There are, however, some real pros on this board that will shortly add their expertise to this issue and you will be well pleased with their suggestions, as I have been over the past many months.
